Train operator London Midland is looking into the conduct of a member of staff after the
The announcement as the train between Wolverhampton and Shrewsbury arrived at Telford led to cheers and laughter from Shrewsbury fans on board.
But it appalled those who were preparing to disembark and head off to their homes in the town.
The slur was revealed on ShropshireStar.com yesterday - leading to a lively debate on the website, Facebook and Twitter.
London Midland today said it would not comment further while an investigation into the announcement was underway but the Gipsy Council has called for the matter to be taken up with the police.
The story was top of the most read list on Shropshirestar.com, with scores of comments from disgruntled Telford residents, who overwhelmingly defended the honour of their town.
Lucy Allan wrote: "I moved to Telford over a year ago. People are kind, friendly and welcoming; it has a great quality of life. I like it and I'm having fun in so many different ways.
"I resent the way those who don't know the town, and don't know the people, have pre conceptions and prejudices about it.
"When I first moved here, a 'nice' lady from Shrewsbury said to me in shocked tones: 'But you are not really going to live in Telford are you?' I was offended at the time - now that I feel like I belong here, I think that lady had narrow minded view of the world - a bit like the train guard."
Robin Git commented: "Oh dear me. I thinks the announcer might be in the mire. To be honest ,why make such a crass comment?
"To blanket stereotype the population of Shropshire's second town seems harsh."
Josephine Papadopoulou added: "It may be that there are a lot of criminals in Telford, however other places aren't exactly full of glowing halos. Train staff have no rights making such prejudiced statements."
But others saw the funny side, like Tora who wrote: "I chose to move to Telford eight years ago after meeting my lovely husband. Like all places, I've found there's good and bad. Overall I'm happy here. I'm also a Shrewsbury Town fan and I went to the match on Saturday. I didn't travel by train, but if I had this comment would have made me laugh. I think perhaps some people have suffered a sense of humour failure."
Jampton Hugh joined in on the joke by writing: "I've lived in Telford for 25 years and only had my car stolen once. Not bad considering. People need to stop feeling offended. The comments were pretty fair. I hope that for balance he was fair on the return trip."
Chri Downes commented: "I was on this train and it was hilarious, it lightened the mood and tension! Several passengers said they wanted to meet the announcer and say thanks for the giggle! But political correctness will see him sacked or warned."
And Matt Joe Irvine wrote: "It does sound pretty funny and it should be taken as a joke. Why do people have to be so offended? I was born and raised in Telford but escaped to Shropshire."
